Authentication is the act of proving an assertion, such as the identity of a computer system user. In contrast with identification, the act of indicating a person or thing's identity, authentication is the process of verifying that identity. It might involve validating personal identity documents, verifying the authenticity of a website with a digital certificate, determining the age of an artifact by carbon dating, or ensuring that a product or document is not counterfeit.
A smart card, chip card, or integrated circuit card is a physical electronic authentication device, used to control access to a resource. It is typically a plastic credit card-sized card with an embedded integrated circuit (IC) chip. Many smart cards include a pattern of metal contacts to electrically connect to the internal chip. Others are contactless, and some are both. Smart cards can provide personal identification, authentication, data storage, and application processing. Applications include identification, financial, public transit, computer security, schools, and healthcare. Smart cards may provide strong security authentication for single sign-on (SSO) within organizations. Numerous nations have deployed smart cards throughout their populations.
An identity document is any document that may be used to prove a person's identity. If issued in a small, standard credit card size form, it is usually called an identity card, or passport card. Some countries issue formal identity documents, as national identification cards that may be compulsory or non-compulsory, while others may require identity verification using regional identification or informal documents. When the identity document incorporates a person's photograph, it may be called photo ID.
An electronic identification ("eID") is a digital solution for proof of identity of citizens or organizations. They can be used to view to access benefits or services provided by government authorities, banks or other companies, for mobile payments, etc. Apart from online authentication and login, many electronic identity services also give users the option to sign electronic documents with a digital signature.
A biometric passport is a traditional passport that has an embedded electronic microprocessor chip which contains biometric information that can be used to authenticate the identity of the passport holder. It uses contactless smart card technology, including a microprocessor chip and antenna embedded in the front or back cover, or centre page, of the passport. The passport's critical information is printed on the data page of the passport, repeated on the machine readable lines and stored in the chip. Public key infrastructure (PKI) is used to authenticate the data stored electronically in the passport chip, supposedly making it expensive and difficult to forge when all security mechanisms are fully and correctly implemented.
Identity document forgery is the process by which identity documents issued by governing bodies are copied and/or modified by persons not authorized to create such documents or engage in such modifications, for the purpose of deceiving those who would view the documents about the identity or status of the bearer. The term also encompasses the activity of acquiring identity documents from legitimate bodies by falsifying the required supporting documentation in order to create the desired identity.
The cédula de identidade is the official national identity document in Brazil. It is often informally called carteira de identidade, "RG" or simply identidade in Portuguese. The card contains the name of the bearer, filiation, place of birth, date of birth, signature and thumbprint of the bearer. Other national documents can legally be used as an identity card, such as a federative unit-issued driver's license, passport or, for minors, a birth certificate. Each card has a unique RG number. As of 11 January 2023, the CPF number will be used as the RG number on new identity cards.

Electronic authentication is the process of establishing confidence in user identities electronically presented to an information system. Digital authentication, or e-authentication, may be used synonymously when referring to the authentication process that confirms or certifies a person's identity and works. When used in conjunction with an electronic signature, it can provide evidence of whether data received has been tampered with after being signed by its original sender. Electronic authentication can reduce the risk of fraud and identity theft by verifying that a person is who they say they are when performing transactions online.

Within Europe as well as French overseas territories and Georgia, the Estonian ID Card can be used by the citizens of Estonia as a travel document.
Extended Access Control (EAC) is a set of advanced security features for electronic passports that protects and restricts access to sensitive personal data contained in the RFID chip. In contrast to common personal data which can be protected by basic mechanisms, more sensitive data must be protected further for preventing unauthorized access and skimming. A chip protected by EAC will allow that this sensitive data is read only by an authorized passport inspection system.

A whole new range of techniques has been developed to identify people since the 1960s from the measurement and analysis of parts of their bodies to DNA profiles. Forms of identification are used to ensure that citizens are eligible for rights to benefits and to vote without fear of impersonation while private individuals have used seals and signatures for centuries to lay claim to real and personal estate. Generally, the amount of proof of identity that is required to gain access to something is proportionate to the value of what is being sought. It is estimated that only 4% of online transactions use methods other than simple passwords. Security of systems resources generally follows a three-step process of identification, authentication and authorization. Today, a high level of trust is as critical to eCommerce transactions as it is to traditional face-to-face transactions.
